Because of its light weight, aluminum tubing offers a greater volume of tubing per weight purchased than steel. Many products benefit from the use of a lighter tubing material, particularly those that require a degree of mobility such as wheelchairs and outdoor furniture. Aluminum tubing also does not tarnish, and it is more receptive to paint and other decorations than other metals, enhancing its aesthetic appeal.http://www.holeealuminum.com/aluminum-tube/
